A PROCESS TO CONTROL THE BLAST FURNACE BURDEN DISTRIBUTION TO IMPROVE PERFORMANCE OF THE FURNACE

摘要

The present invention relates to a process to control the blast furnace burden distribution to improve performance of the furnace, characterized by comprising the step of defining a shape of a heap of burden in terms of a normal distribution curve - where, y is the height of the heap at r radial location, B is a location of the peak, and being associated with an outer stream of the trajectory, calculated from the trajectory information, and applying two device relationships to determine 'A', and 'C':- for metallics (consists of sinter, iron ore and flux) :- A=mC+d, for coke A=nC+e, and for conservation of mass:- based on decided charging sequence.
